Chrysanthemum plant named &#39;aramis white&#39;

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Aramis White’, characterized by its upright, outwardly spreading and uniformly rounded plant habit; moderately vigorous growth habit; freely branching habit; dense and full plant habit; dark green-colored leaves; uniform and freely flowering habit; and relatively large decorative-type inflorescences that are snow white in color.

BOTANICAL DESIGNATION

Chrysanthemum×morifolium

CULTIVAR DENOMINATION

‘ARAMIS WHITE’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Aramis White’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in October, 2009 of Chrysanthemum×morifolium ‘Bardi’, not patented, as the female, or seed, parent with Chrysanthemum×morifolium ‘Elani White’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2010.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2011. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Aramis White’. These characteristics in combination distinguish ‘Aramis White’ as a new and distinct Chrysanthemum plant:

1. Upright, outwardly spreading and uniformly rounded plant habit; moderately vigorous growth habit.

2. Freely branching habit; dense and full plant habit.

3. Dark green-colored leaves.

4. Uniform and freely flowering habit.

5. Relatively large decorative-type inflorescences that are snow white in color.

Plants of the new Chrysanthemum differ from the female parent, ‘Bardi’, in the following characteristics:

1. Plants of the new Chrysanthemum are taller and more upright than and not as broad as plants of ‘Bardi’.

2. Plants of the new Chrysanthemum have smaller inflorescences than plants of ‘Bardi’.

Plants of the new Chrysanthemum differ from the male parent, ‘Elani White’, in the following characteristics:

1. Plants of the new Chrysanthemum are taller than plants of ‘Elani White’.

2. Leaves of plants of the new Chrysanthemum are darker green in color than leaves of plants of ‘Elani White’.

3. Plants of the new Chrysanthemum have decorative inflorescences whereas plants of ‘Elani White’ have daisy or single-type inflorescences.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Rosalba White’, disclosed in U.S. Plant Pat. No. 21,803. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Rosalba White’ in the following characteristics:

1. Plants of the new Chrysanthemum were shorter than plants of ‘Rosalba White’.

2. Leaves of plants of the new Chrysanthemum were darker green in color than leaves of plants of ‘Rosalba White’.

3. Plants of the new Chrysanthemum had smaller inflorescences than plants of ‘Rosalba White’.

4. Ray florets of plants of the new Chrysanthemum were snow white in color whereas ray florets of plants of ‘Rosalba White’ were creamy white in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Aramis White’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the spring and summer and under cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 18° C. to 21° C. and night temperatures ranged from 10° C. to 15° C. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
